' The objects of the invention are to provide improvements 1n unloading means for dump wagons, which are designed topermit unloading from the extreme rear end of the a wagon'and utilizing the end gate as achute which when loweredwill deliver the load from either side of the wagon or directly to the rear thereof, thus permitting the wagon to unload from either side beyond the extreme 10 end thereof without backing up to the unloading position, or permitting it to unload directly from the rear when it is backed to the unloading position.

In this device the end gate can also be 1 lifted up on pivots and upon its upper edge so that the load can be discharged quickly from the open rear end of the wagon.

The device includes a rear end gate hav-- ing projecting journals upon its upper and lower edges and corresponding bearings upon the rear edges of the side walls of the wagon,

. in which the journals are detachably secured thus permitting the end gate to be lowered when it is desired to employ it as a delivery chute, or to be raised when it is desired to discharge the load directly from the rear" end of the wagon.

an end gate having side delivery chutes, at its extremities and also having cover plates 1 movable thereover to prevent theescape of the load when the gate is ra1sed into place.

The invention also includes the provision of a guard'plate'at its longitudinal rear edge to prevent the load from passing over the rear edge when the gate is lowered and a rearwardly extended chute therein and a cover plate therefor which can be detached when it is desired to discharge the load rearwardly through the gate.

The invention is hereinafter further described, illustrated in the accompanying drawings and specifically pointed out in the Fig. 3 is a transverse section thereof;

Fig.4 is a transverse section therethro'ugh at right angles to the section of Fig. 3'; I V Fig.6 is aplan thereof showing the gate lowered;

Fig. 6 is an end elevation thereof. In the accompanying drawings, A, A, represent the side walls of the wagon,'B represents the floor thereof, C is the end gate whi ch is formed preferablyof sheet metal and its longitudinal edges are reinforcedwith angle bars D D, and the journals E, E, project from the extremities thereof,*at each end. By means of'thesejournals and vertically spaced bearings F, F, therefor upon "thevvertical rear edges of the side.- walls of the dumpwagon, the end gate maybe suspended from =its'upper ed-ge 'at F" and raised-to permit the load to be discharged directly from the wagon, or it maybe hinged at its'lowe'r edge at F and dropped down as'show'n in Figure lso that the loadwill pass through it when thewagon is tilted for this purpose) "By means of the construction shown the load may be discharged at the option of the driver in either of three directions; that is from either side of the wagon or through the rearretaining wall of theend gate. The device also includes the provision of To permit-of these actions, the' 'end' gate is'bent over at right angles at C" t0 forma a rear retaining wall whenthe gate is lowered; and is also inclined outwardly at C C on each side to form side delivery chutes, having sidewalls, C C the edges'of which are secured to the aforesaid angle barsiD', To prevent the load. from passing out of these side chutes when theend gate is raised, cover I plates 1, I are p1'OVld6d,fthe'lIIIIGIQGXtI'GIIllties of; which are secured by inserting their reduced ends I I underneath the central flatwail C of the gate as shown in Figures 1" '90 an'3. a These coverplates are provided with raised retainingfwalls 1 F, at their outer ends that prevent the load from escaping from the, side of the *car' when it-is desired to rdeliver the loaddirectlyto the rear, and not through the side chutes. f Thes e cover platesacan easily be pulled out when itjis desiredto-discharge 'whi'chthe journals are "detachably secure by dropping retaining pins P, through the directly to shown, a cover J isoremoved from an opening C in the retaining wall G and the load is discharged through the chute formed by projecting of the walls C from, p

the sides of the opening.

The cover J is secured by means of thumb 7 screws K, K, fitted'in slots L, L, in the walls of the cover andchute. Chains M, M, suspend'the end gate when lowered. The bearings F, F for the journals of the eiid'gat Y may be simply constructed of Inetal straps G, G, having projecting endsGbetween forced longitudinal edges, terminated by projecting journals and provided with a marginal outerretaining wall at right angles thereto,saiid wall having a discharge open- I or analogous device, a plate having rein- 1 indand a detachable cover for said opening ing and a detachable cover for said opening.
